Australian school libraries have an expressed need to organise resources according to Australian Curriculum outcomes. Education Services Australia (ESA) has aligned digital resources to the Australian Curriculum since 2011, publishing them on platforms including Scootle. The Schools Catalogue Information Service (SCIS) at ESA creates and distributes MARC records to 93% of Australian school libraries, but has not traditionally provided curriculum-alignment data. This paper describes a trial in which headings from a linked data subject vocabulary (the Schools Online Thesaurus) in MARC records are supplemented with URIs for the purpose of consuming Australian Curriculum alignment data. A widget is presented to demonstrate possible downstream applications.
